Google Play Reviews

  1. Avijit Kar-avatar

    I liked it. It's very cautious. Everytime when I open any app, it pops up. Also when I open an app after minimizing it, I need to give the diagram. Resetting process is not hard for me (it's hard for others, they don't know my lucky no.) as I just need to tell my lucky no. which is asked the first day. Edit: after the last update, AppLock has deteriorated in its functioning, sometimes it does not work, and the apps open without asking for the pattern.

  2. Cameron McNally-avatar

    Cameron McNally


    This app is great!!! If you have WhatsApp or Google then LOCK IT!! I chose to lock WhatsApp, Google, my contacts, Netflix, Spotify and Gallery. I am only 9 years old but I would recommend you try it because all you do is install it, make your passcode for all the apps then choose the apps to lock so it's a pretty good app

  3. Lakshmi Durga-avatar

    Worst app. Why forgot password option is available in this. It's a personal lock. But anyone can open by using forgot password. There is nothing personal security in this app. It's my experience and my review.

  4. FAITH FRANK-avatar

    I love this app. But, the adds keep coming and, I don't know if it will stop working after the free days are over. It saves me the fear, whenever my phone is wirh someone.

  5. Hassan Cooper-avatar

    This app is amazing... for real!!, all other app locks stops sometimes so you don't feel safe all the time and you have to restart them to make em work again but this "not even a single second "

    Garfield Parkside


    So far good, the other apps I tryed would let anybody bypass it by turning the phone off then on and go straight to what ever app you wanted to. I have not tried this one yet. We'll see. I already had four apps do it so I'm going to cross my fingers
